“3414”肥效试验对西瓜产量的影响及推荐施肥量分析

The Effect Fertilizer on Watermelon Yield and the Optimal Fertilization Amounts Using of “3414” Test

为了给西瓜生产提供施肥理论依据,采用"3414"肥效试验研究了配方施肥对西瓜产量的影响,以及施用氮磷钾肥的肥料效应。结果表明:与对照相比,各配方施肥处理西瓜的产量均有所提高;其中以N2P2K2处理肥料配施最佳;本试验条件下西瓜667m2最佳经济施肥量为氮(N)18.25kg、磷(P2O5)10.14kg、钾(K2O)13.81kg,667m2最高产量施肥量为氮(N)20.26kg、磷(P2O5)10.86kg、钾(K2O)14.29kg。

The ＂3414＂ experiment was carried out to study the effect of formulated fertilizer on yields of watermelon, and ef- ficacy of N, P, K fertilizers. All fertilization treatments improved yield over check, the treatment of N2P2K2 reached the highest yield. Under the experiment condition the optimum N, P and K fertilization for the highest watermelon yield were 20.26,10.86 and 14.29 kg.per 667 m2,and the best economic N ,P and K fertilization were 18.25,10.14 and 13.81 kg per 667 m2.
